Find the zeros of the function.Enter the solutions from least to greatest.
f (x)=(x -3)(2x -8)f(x)=(x−3)(2x−8)

Answers

Answer 1
Answer:

Answer:

The zeroes of the function are: 3 and 4

Step-by-step explanation:

Zeroes of a function are the values on which the function produces zero output. To find the zeroes of a function, the function is put equal zero and the values of the variable are found using the equation. The values of x are the zeroes of the function.

Given function is:

f(x) = (x-3)(2x-8)

Putting the function equal to zero

f(x) = 0\n(x -3)(2x -8) = 0\nx-3 = 0\nx = 3\n2x-8 = 0\n2x = 8\n(2x)/(2) = (8)/(2)\nx = 4

We get two values for x, x=3 and x=4

Hence,

The zeroes of the function are: 3 and 4

The price of apples went from $0.30 per lb to $0.90 per lb in three years. Find the rate of change of the price of apples.

Answers

Answer:

Hence, the rate of change of the price of apples is:

                             $ 0.20 per year.

Step-by-step explanation:

Let P denote the price of apples.

It is given that the initial price of apples is: $ 0.30 per lb.

i.e. P(0)=$ 0.30 per lb.

Also, the price of the apples after three years is:  $ 0.90 per lb.

i.e.  P(3)=$ 0.90 per lb.

Hence, the rate of the change of the price of apples is calculated by:

Rate\ of\ change=(P(3)-P(0))/(3-0)

Now on putting the value in the formula we obtain:

Rate\ of\ change=(0.90-0.30)/(3-0)\n\n\nRate\ of\ change=(0.60)/(3)\n\n\nRate\ of\ change=0.20

                          The rate of change is:

                             $ 0.20 per year.
